Detector Scientist

Within the framework of the upgrade of the facility (https://ebs.esrf.fr/about-us), the ESRF started the study and prototyping of a new high-performance 2D hybrid pixel X-ray detection system based on a novel readout concept and optimised for the new generation high-energy, high-brilliance synchrotron radiation sources. The project continues as part of a international collaboration called Xidyn, composed of five European partners, and aims at concluding the R&D phase and preparing the development and engineering of the final detector.

You will integrate a team of scientists and engineers specialized in X-ray detection, electronics and software to finalise the last stages of the R&D studies, evaluate the final system performance and prepare the development of the full-size X‑ray detection systems. You will contribute to the dissemination of the results in scientific conferences and publications and collaborate with other research laboratories, academic and industrial partners at an international level.

The duties of this position include:

• Contribute to the preparation of the next run of prototypes and/or full-size demonstrators in collaboration with project partners,
• Estimate the detection performance and limitations of the full-size final detectors with Monte Carlo simulation tools,
• Implement specific characterization and data analysis methods to assess the data quality of the detectors,
• Define and implement effective calibration schemes. Assess the quality of calibration procedures with experimental results,
• Contribute to the X-ray characterisation of detector prototype assemblies built with existing test readout ASICs and pixelated sensors by using synchrotron beams and conventional laboratory sources,
• Characterise the response of the high-density compound sensor materials under high-flux illumination at high energies up to 100 keV.
